Safety opening and closing door for transformer short circuit test platform
The invention discloses a safety opening and closing door for a transformer short-circuit test platform, and the door comprises a door body which has an opening state and a closing state; the linkage structure is connected with the door body and driven by the door body, and the linkage structure is provided with a first linkage position and a second linkage position which correspond to the opening state and the closing state respectively; the double-throw switch comprises a switch blade, a grounding side contact and a power supply side contact, the switch blade is connected to the linkage structure, when the linkage structure is located at the first linkage position, the switch blade moves to be connected with the grounding side contact, and when the linkage structure is located at the second linkage position, the switch blade moves to be connected with the power supply side contact. And the knife switch moves to be connected with the power supply side contact. According to the invention, residual charges released by a transformer end can be ensured to be completely released when a worker enters a laboratory, the effect of power-off protection when the door is opened is achieved, and the risk of electric shock is completely eradicated.
本发明公开了用于变压器短路试验平台的安全开关门，包括：门体，具有打开状态和关闭状态；联动结构，其与所述门体相连并由所述门体驱动，所述联动结构具有与所述打开状态和所述关闭状态分别对应的第一联动位和第二联动位；以及双掷开关，所述双掷开关包括闸刀、接地侧触头以及电源侧触头，所述闸刀连接于所述联动结构，当所述联动结构处于所述第一联动位时，所述闸刀移动到与所述接地侧触头连接，当所述联动结构处于所述第二联动位时，所述闸刀移动到与所述电源侧触头相连。本发明可以保证工作人员在进入试验室时变压器端释放残余电荷已经释放完成，起到开门即断电保护的效果，杜绝触电风险。
